FLOOR STRUCTURE.

Specification of Letters Patent.

Patented Aug. 1, 1922.

Application filed January 3, 1922. Serial No. 526,650.

To @ZZ whom t may concern:

Be it known that I, VALsY E. RowLAND, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Floor Structures,of which the following is a specification.

This invention relates to floor structures, and its object is to providea novel and improved structure of this kind composed of hollow blocks ortiles, and concrete or other analogous material, and also to provide afloor structure which is cheap and possesses great strength anddurability.

Other objects and advantages of the invention will be pointed out in thedetailed description appearing hereinafter, and in order that theinvention may be better understood, reference is had to the accompanyingdrawing' forming a part of this specification.

In the drawing,

Figure 1 is a perspective view of one of the hollow blocks or tiles; Fig. 2 is a sectional view of a floor in which the block shown in Fig. lis used, and Fig. 3 is a perspective View of a spacing element.

In carrying out the invention, there is provided a hollow building blockcomposed ot' parallel bottom and top walls 10 and 11, parallel end walls12 and 13, an integral longitudinal web 14 extending between the endwalls parallel to the bottom and top walls, and transverse webs l5extending between the bottom and top walls and the longitudinal webparallel to the end walls.`

The block is made of clay, concrete or any other suitable materialusually employed in the construction of building blocks, and it can bemade in various sizes. The webs 14 and 15 define a series of cells 16located on one side of the web 14, and another series 1T located on theother side of said web. These cells extend horizontally through theblock and open through the sides thereof.

Fig. 2 shows the wall block of Fig. l employed in a floor construction.Here the blocks are laid in horizontal rows and in endwise spacedrelation to bring the grooves 1S of adjacent blocks opposite each other.The blocks are retained in spaced relation by spacers 19 which bridgethe blocks at the bottom and are supported by having their ends seatingthe bottom grooves 18, said ends being reduced to bring the bottomsurface of the spacers flush with the bottom surface of the blocks. Ontop of the blocks is placed the layer 2O of concrete forming the floorsurface, said material also being poured between the blocks to form thefloor joists or beams 21, which latter may be provided with areinforcement 22. The spacers 19 close up at the bottom the spacesbetween the blocks, and serve as a moisture absorbing surface betweenthe concrete material forming the joists and the plaster or otherceiling material 23, and they also assure the same width of all the,joists The end grooves 18 of the blocks produce an irregular surface towhich the concrete material forming the floor joist-s iirmly adheres,and the blocks are securely interlocked with and united to the joists.The reduced ends of the spacers 19 gromres entirely, so that theconcrete material forming the joists may enter said grooves above theends of the spacers and bond the saine in place.

I claim:

l. A floor structure comprising blocks laid in rows and spaced at theirends, a layer of plastic material on said blocks, said material alsolling the spaces "between the ends of the blocks to form Hoor joists,and spacing' elements between the blocks at the bottom thereof, the endsof the blocks having transverse grooves in which the ends of saidelements seat and are supported, and said block ends having othertransverse grooves entered by the material forming the joists, said endsof the spacing elements lilling only portions of the first mentionedgrooves to permit the joist material to enter said grooves above saidends of the spacing elements.

2. A Hoor structurecomprising blocks laid in rows and spaced at theirends, a layer of plastic material on said blocks and also lling thespaces between the ends thereof to form floor joists', and spacingelements between the blocks at the bottom thereof, the ends of theblocks having' grooves in which the ends of the spacing elements seatand are supported, and said ends being reduced in thickness to partlytill the grooves and locate the bottom surfaces of the spacers flushwith the bottom surfaces of the blocks, the spaces in the grooves abovethe reduced ends of the spacing elements being also filled with theaforesaid joist material.

In testimony whereof 1 aiiX my signature.
